Hand-held implement for transferring a film of e. g. adhesive or coating or colored material from a backing strip wound on a supply reel to a substrate

Abstract

The present invention relates to a hand-held implement for transferring a film of, e.g., adhesive or coating or colored material from a supporting strip wound on a supply reel onto a substrate, said implement comprising a housing, a pressure-exerting part projecting from the housing and with a pressure tip guiding and deflecting a supporting strip section, and two mounting and/or carrying devices arranged in the interior of the housing for the supply reel and a take-up reel for the supporting strip taken off from the supply reel and guided and deflected round the pressure-exerting part, the housing being open for the purposes of replacing a cassette carrying the supply reel and the take-up real, and a positioning device being provided for positioning the cassette in the housing.

I claim: 
     
       1. A hand-held device (1) for transferring a film (45) of, for example, adhesive or coating or colored material from a backing strip (6) onto a substrate (14), comprising a housing (2), a pressure exerting part (9) mounted on the housing and projecting therefrom and having a pressure tip (11), a cassette (3) which can be positioned in the housing (2) by means of a positioning device (7) and two bearing means arranged in the cassette interior for bearing a supply reel (4) and a take-up reel (5), from which a backing strip (6) in the form of a loop (6a) extends around the pressure exerting part (9) and is deflected about the same, wherein the housing (2) can be opened laterally for replacing the cassette (3), wherein a holding device for the loop (6a) is arranged on the end section of the cassette (3) facing the pressure exerting part (9), which holds the loop (6A) in such a position that the loop (6a) can engage the pressure exerting part (9) by a lateral engagement movement of the cassette (3) towards the housing part (2a) characterized in that the cassette (3) comprises a base wall (16) on which the bearing means for bearing the supply reel (4) and the take up reel (5) are arranged, the housing part (2) comprises a guide part (8) for the cassette (3) in which the cassette (3) can be inserted in a forwardly displaced insertion position during lateral engagement towards the housing (2) and can then be rearwardly displaced in the guide (8) into an end position. 
     
     
       2. A hand-held device (1) according to claim 1, characterized in that the holding device is formed by two forked projecting arms (25) arranged between the backing strip sections of the loop (6a). 
     
     
       3. A hand-held device (1) for transferring a film (45) of, for example, adhesive or coating or colored material from a backing strip (6) onto a substrate (14), comprising a housing (2), a pressure exerting part (9) mounted on the housing and projecting therefrom and having a pressure tip (11), a cassette (3) which can be positioned in the housing (2) by means of a positioning device (7) and two bearing means arranged in the cassette interior for bearing a supply reel (4) and a take up reel (5), from which a backing strip (6) in the form of a loop (6a) extends around the pressure exerting part (9) and is deflected around the same, wherein the housing (2) can be opened laterally for replacing the cassette (3) wherein a holding device for the loop (6a) is arranged on the end section of the cassette (3) facing the pressure exerting part (9), which holds the loop (6) in such a position that the loop (6a) can engage the pressure exerting part (9) by a lateral engagement movement of the cassette (3) towards the housing (2a), characterized in that the holding device is formed by two forked projecting arms (25) arranged between the backing strip sections of the loop (6a). 
     
     
       4. A hand-held device according to claim 2 or 3, characterized in that the forked arms (25) converge diagonally or rounded forwards at their free ends. 
     
     
       5. A hand-held device according to any one of claims 2 or 3, characterized in that the loop (6a) is laid around the free ends of the forked arms (25). 
     
     
       6. A hand-held device according to claims 2 or 3, characterized in that the section of the loop (6a) extending between the free ends of the forked arms (25) is located in the insertion position forward of the pressure exerting part (9). 
     
     
       7. A hand-held implement as claimed in claim 3, wherein the distance (e) of the arms (25) from one another and their length are larger than the dimensions of the pressure-exerting part (9). 
     
     
       8. A hand-held implement as claimed in claim 3, wherein the length of the arms (25) is greater than the relevant length of the pressure-exerting part (9), that the distance (e) of the arms (25) from one another is less than the pressure-exerting part (9), and that the arms (25) can elastically bend sideways.
